DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 404,627, dated June 4, 1889. Application filed June 21, 1888. Serial llo. 277,780. (ModeL) To all whom it may concern Be it known that I, ABRAM HURSH, a citizen of the United States, residing at Yellow Springs, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in Door Stops and Holders, of which the following is a specification.

The object of my invention is to provide a device in the nature of a door-stop which is also adapted to holding the door in an open position, the device, when used as a doorholder, being automatic in its nature and adapted to be readily operated to release the door when desired, means being provided whereby the said device may be used as asimple door-stop. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a device embodying my invention, shown in use in connection with a door of ordinary construction. Fig. 2 is a perspective view of the same with the upper portion of the casing removed, showing the operating parts of the device, the door-holderbeing shown in a closed position. Fig. 3 is a perspective view of the same, showing the door-holder in an open position. Figs. 4 to 7, inclusive, are detail views of the respective operating parts. Fig. 8 is a sectional elevational view of the holder, showing the method of connecting the operating parts together to form a simple door-stop.

Like parts are indicated by similar letters throughout the several views.

In the said drawings, A represents the outer casing, which is adapted to be secured to the base-board or to any other convenient point of attachment directly behind the door in such a position that the door will swing back against the same. Extending longitudinally through the casing is aplunger a, provided at the outer end with a cushion of rubber or other suitable material a, against which the door is adapted to swing.

Pivoted in the casing A at a point b, just back of the plunger a, is a curved arm B, substantially of a U shape, with one straight side B ,which carries at its extremity the pivotal point. This arm B is provided at the outer extomity with a ball or knob b, of rubber or other suitable material, adapted,when in a normal position,to rest in a countersunk opening 11 in the edge of the outer casing A. The curved arm B is provided at its base, at a point near the junction of the straight portion with the curved portion thereof, with a notch b adapted to be engaged by a springcatch If, the inner end of which is secured to the casing A. Located in the arm B a short distance from the pivotal. point 6 is a proj ecting pin or stud 19 which projects into an opening a in the plunger a. This opening a is preferably made of a slightly-elongated form, so that the plunger a may have an independent longitudinal movement without coming in contact with the stud b Immediately under the arm B and about the pin or stud which forms the pivot therefor is a small spring a, one end of which is secured to the casing A and the other to the straight portion 13 of the arm'B in such a manner that the tension of the said spring is adapted to bring the curved arm outwardly to the position shown in Fig. 3 when released by the spring-catch b A small coil-spring a is preferably inserted just under the head a of the plunger a, which serves to keep said plunger pressed outwardly through said casing A, with the rear end of the opening a in contact with the stud I)? in the arm 13.

The plunger a is supported at the rear end on a suitable bearing d on the main casing A, and is adapted, when forced longitudinally through the casing A, to come in contact with the spring-catch If, and thus release the arm B, which, through the medium of the spring 0, will be forced outwardly to the positions shown in Figs. 1 and 3.

The operation of the device is as follows: The main casing is secured in such a position that the edge of the door is adapted to come against the stop or cushion a of the plunger a, the main casing A being so located that the end I) of the arm B stands beyond the edge of the door when the same is in contact with the cushion a. As the door comes in contact with the cushion a the spring-catch b will be forced out of the notch b and the arm B will be forced to the position shown in Figs. 1 and 3, with the knob b on the front side ofthe door, thus holding the same firmly in position. hen it is desired to release the door from the holder, the door is forced back against the plunger at, bringing the end of the slotted opening a against the stud Z), which thus carries the arm B back to its 11ermal position until the spring-catch b engages in the notch U and holds the same. As the stud 1) moves in the are of a circle about the pivot I), the inner end of. the plunger will be moved laterally as the arm approaches itsnormal position. The end of the plunger will therefore pass the spring-catch without engaging the same, a space f being left between the end of the spring-catch and the casing for this purpose. The arm is thus forced to its normal position and the spring-catch left free to engage the notch in said arm. Vhen the pressure is removed from the plunger, the spring about said plunger returns it to its nor mal position against or in front of the springcatch, so that a subsequent longitudinalmovement of the plunger will force the said catch out of engagement with said arm.

The casing A is preferably provided with small cushions c e, of rubber or other suitable material, adapted to form stops for the arm B when forced in either direction to re lieve the casin g from any sudden jar thereon caused by the action of said arm.

The plunger is provided with an opening to, which stands opposite to similar openings in the side of the casing A. A pin a is adapted to be inserted through the casing in said opening a, as shown in Fig. 8, and thus hold the plunger a against longitudinalmovement through the said casing.

\Vhen it is desired to use the device simply as a door-stop, the pin a is inserted in the openings described, thus holding the plunger firmly against longitudinal movement of the spring-catch If. It will be seen that when in this position the operating parts will be held from movement and the device will act as a simple door-stop. It is evident that the pin a may be placed in the arm B or any other portion of the operating mechanism with the same result. 7

Having thus described my invention, I c1aim-- 1. In a door-check. having a suitable frame or casing, a spring-actuated arm, a catch to engage said arm, and an operating-plunger adapted to release said catch, substantially as specified.

2. A door-check having asuitable frame or casing, a spring-actuated arm, a catch to engage said arm, a plunger to release said catch, and means, substantially as described, for connecting said arm and plunger, so that a longitudinal movement of said plunger will cause said arm to be engaged with said catch, substantially as specified.

3. An operating-phinger, a curved pivoted arm, a catch to engage said arm, adapted to be operated by said plunger, a projecting stud in said arm engaging in a slotted opening in said plunger, and a spring connected to said arm and adapted to move the same when released by said catch.

4. The outer casin g, the operating- Hunger therein, a curved arm pivoted to said casing, a catch operated by said plunger, adapted to engage said arm, and elastic cushions in said casing to limit the movement of said arm, substantially as specified.

5. The outer casing, the door-holding arm pivoted therein, the spring-catch for retaining said arm, a plunger for releasing said spring-catch, the operatingspring for said arm, and means, substantially as described, for connecting said plunger and arm, whereby the arm may be returned to its normal position by pressing on said plunger, substantially as specified.

6. The outer casing, the operating-plunger having a cushioned end extending into said casing, a swinging door-holding arm operated by said plunger, and a pin, substantially as described, for connecting the operating parts to the casing and thus holding said arm from movement when the cushioned end of said plunger is used asa simple door-stop.

7. The outer casing, the pivoted arm therein, the spring-catch adapt-ed to engage said arm, the plunger adapted to operate said spring-catcl1,tl1c operating-spring connected to said arm, the projecting stud on said arm engaging with the slotted opening in said plunger, and the spring adapted to hold said plunger in its normal position, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 16th day of Julie, A. .l). 1888.
